Underdog Hatton warned he must find Pep to floor all-time great Mayweather

RICKY HATTON has got to knock out Floyd Mayweather if he is going to claim the WBC welterweight title in Las Vegas on Saturday — according to one of only two men who has fought them both.

Canadian Tony Pep took Mayweather the 10-round distance in 1998 and three years later managed to bloody Hatton before being stopped in four rounds at Wembley Arena.

Along with Mexican Jose Luis Castillo, Pep is in a unique position to assess the qualities of both fighters ahead of their super-fight and cannot see a way for the Englishman to win if it goes the distance.
